Predictive factors for changes in quality of life among children and adolescents in youth welfare institutions.

Purpose: Children and adolescents living in youth welfare institutions often have a below average quality of life (QoL), for reasons that include developmental difficulties, history of traumatic experiences, and mental disorders. Youth welfare measures are needed that would have a positive impact, but there is a lack of longitudinal research on which measures are most effective. This study investigated what factors are associated with an improvement in QoL during residential stay.
